Model Predictive Control for a Five-Phase PMSM Drive Using Four-Leg Five-Phase Inverter

In this paper, a cost-effective four-leg five-phase inverter is proposed for controlling permanent magnet synchronous motors (PMSM). In this topology, one of the phases of the five-phase PMSM is connected to the midpoint of DC voltage sources. The mathematical model of four-leg five-phase drive is derived. In addition, the discrete model of the five-phase PMSM is developed. The model predictive control for this motor is developed to regulate the motor speed. Simulation results are presented to validate the effectiveness of the proposed drive and control method.
